Need Help ASAP!! Multiple Symptoms, [LOTS OF PICS]

Indoor grow, 430w HPS, 5 gallon buckets, 3 plants (only 1 is sick), pH of water: 6.4-6.8, unknown TDS, unknown soil pH, BioCanna organic nutrients, 31 days flowering. ~26 degrees Celsius and ~50% humidity.

Stunted growth, can't support it's own weight (It's nearly 6'6" including the bucket tho); first thing to show on an otherwise green leaf is very small orange speckles, then the leaf turns yellow, then brown; however some leaves' first sign is yellowing tips and edges. Purple stems (might not be a problem, other plants showed it a bit too so it could just be the strain)

Any help with diagnosing the problem and the remedy will be greatly appreciated.

This is one of the healthier plants, it has a hard time supporting it's own weight too.

She needs calcium and phosphorus.
BioCanna is good stuff. Are you using full dosage?

First of all, thank you! And yes I'm using full strength BioFlores (the flowering nutes, 2.5-2.0-5.0) along with Hygrozyme.

Should I mix a more diluted food for this one plant?
How can I get more calcium and phosphorus into her?

I'm not an organic grower and I don't know if you want to try and stay organic.

I would hit her with some cal/mag, available at any garden supply, and some Canna PK 13/14, available at your hydro store.
Then watch her take off.

Edit: Definitely stick with the full strength nutes, those nutes aren't very strong at all.

Yup,,,cal-mag+

does your water contain chlorine?

the other thing i would say is put some stakes in the dirt so your plants can use it to lean on .

Thanks everyone, as far as staying organic; I would rather go non-organic to have this plant be healthy than to lose the bud from it, I'm going to go get some Cal-Mag tomorrow and I'll look into PK 13/14.

My water does have chlorine but I use a water filter and I leave the water in a big jug for a couple days before I use it.

I guess I'll be getting some stakes for these girls when I go shopping.


If anyone knows organic ways to add calcium and phosphorus I would really like it to hear it, otherwise I'll be going non-organic; not too big of a deal to me, but I would rather stay organic if I can.


Thanks guys.

if you are having trouble with the plant being unable to support its own weight, just stick a stick in the dirt and tie that plant to it!

another thing to think about for your next grow is a trellis. In the November 2008 High Times, they show you how to make a great trellis that will be there for grows and grows

look for page 46 or something like that, if you're interested.

Boil some egg shells and add a couple tablespoons of epsom salts, stir, filter shells out and let cool. I had similar issues dealing with my crappy water and it works well.

where can I find epsom salt?

How many shells should I use for 2 litres of water?

Epsom salts can be bought at any supermarket or big box type store....or pharmacy. Look in the first aid area, if not there it could be in the bath/body section. As for the shells, I usually do a dozen for a 3 gallon pot, you really cant over do it so don't worry, you are basically extracting a bit of calcium from the eggs is all. Boil them for about 20 minutes then strain and cool.

this is just a question, but couldnt you use some antacid tablets? all it is is calcium bicarbonate. is that the correct type of calcium you are looking for or some other type of calcium?

the other route would be to go to a hydroponics store and ask the workers there for the micronutrients or calcium and phosphorus.

lower your ph to 6 - 6.2 for soil ... lower humidity during flower to 30 - 40 %. I would use a sugar additive during flower as well, I use molasses. Its normal for plants not to be able to hold themselves up .. personally i tie up the cola, and use x mas hooks to hold up branches, hook branch to main stem .. on a 6 plus footer you will need to tie to ceiling, walls will hurt growth ..
